I had a similar experience recently. It was also one of the scariest experiences of my life. Afterwards I spoke with my doctor about it, and they used the terms "anxiety attack" or "panic attack". In my case, it was brought on by a combination of eating poorly, drinking too frequently, sleeping irregularly, and letting myself become stressed out about work in my off hours. It was bad enough that I spent the following week in-patient at a hospital. That said, having three structured meals a day, sleeping regular hours, and not having my phone - I felt like a new person by the end of the week. Not sure if this relates to your experience, but the lesson I learned was: Take real vacations. Where you are not tethered to your phone, social media, work calls, PagerDuty, social calls, etc. You can just eat, drink, sleep, breathe, and take in the moment. Even if it is just for a day, take time to remember what it means to be human. Edited: for tone
